A penumbral eclipse of the Moon occurred on 20 March, 1801 BC UT Old Style, with maximum eclipse at 01:38 UT. This very subtle penumbral eclipse was essentially invisible to the naked eye; though it lasted 2 hours and 13 minutes, just 22% of the Moon's disc was in partial shadow (with no part of it in complete shadow).

The penumbral eclipse lasted for 2 hours and 13 minutes. Maximum eclipse was at 01:38:40 UT.
